Luminaries versus planets
Astrologers commonly call the Sun and Moon “luminaries.” They are not planets in astronomy, but astrology groups them with the planets because all are interpreted as chart factors.
Personal, social and outer planets
The Sun through Mars are often called personal planets because they move relatively quickly and vary more among individuals. Jupiter and Saturn are social planets. Uranus, Neptune and Pluto move slowly and can describe generational patterns.
Sign, house and aspect change the expression
A planet is not interpreted in isolation. Its sign describes style, its house describes life area, and its aspects describe relationships with other chart factors.
Traditional and modern rulerships
Classical astrology assigned the seven visible planetary bodies to the signs. Modern astrology added Uranus, Neptune and Pluto as rulers or co-rulers of Aquarius, Pisces and Scorpio in many schools.
Astronomy note
The physical properties of planets are studied by astronomy. Astrological meanings are symbolic traditions and should not be confused with scientific effects demonstrated by planetary science.
